Confirms: 4GB vram & 1x8pin power connector + silent operating fans

Speculation: Tonga (285) "Full-Feature" w/
-better power optimizations
-4gb Memory vs 2gb
-32 Core Units vs 28
-2048 Steam Processors vs 1792
-128 Texture Mapping Units vs 112
-384bit Memory Bus vs 256bit
-288GB/s Memory Bandwitch vs 176GB/s

a 970/960ti combatant, hopefully around $250

A single 8 pin connector is not unusual for the R9-285, and the R9-380 is the same Tonga chip, with perhaps a little better efficiency.

A single 8 pin connector makes sense.

For me this is just a 285 with 4GB. Maybe the full Tonga. Will have to be sub $200.

4Gb indicates that is 256bits. There're no 384bits Tonga. Full Tonga (M295X) has 256bits and 4GB.

But Tonga performs better with less actual memory bandwidth such that 256bits keeps up with the 384bits of previous cards.

As Much as I lust for Fiji, Hawaii plus tonga's updated GCN is really my ideal "stop gap" till 14nm, oh and it needs to be cheap. Hopefully with dx12 xfire becomes a much more reasonable solution, instead of trying to stick with single cards

Yea I have a feeling this card or the yet to be released 3gb gtx960ti will be the sweetspot for my next 200/250$ card.

edit:

I thought this card was a r9 380X not plain 380? OP should fix this.

The pics say 380 and not 380X, so I guess it's the 380.

The 380X is probably a step up. Maybe a clockspeed bump?

click the link in the op.

"Gigabyte Radeon R9 380X G1 Gaming", but the box says 380?.

Full tonga will be 380x I thought ,rebranded 285 will be the plain 380.

Yes, it's supposedly an R9-380 box.

I have no idea why the X was added to the story.

Logically:

380=285
380X=full 285

But the OP also says "speculation".

If you translate the page, the article apparently compares the pictured card to the 290X...

So, who knows?

Lower power requirements, more speed.

I've gone from intrigued to aroused........... [evil grin]

It appears to be the same power requirements as far as I can tell.

How very interesting. Minimum power supply requirement is 500 watts.

http://www.gigabyte.com/products/product-page.aspx?pid=5212

All the full size 970 they sale have 550 watts power requirement.

http://www.gigabyte.com/products/product-page.aspx?pid=4821#ov
The 290 and 290X they sale has a 600 watts power requirement.


Their 960 has a 400 watts power supply requirement.

I can't draw any conclusion from that

The board partners typically just copy NV/AMD's recommendations, maybe add another 50W if they overclock it. I wouldn't read too much into it if you're going cross-vendor, since they overestimate to different degrees.

The Gigabyte GTX 960 only requires a 400W power supply - though, surprisingly, it has both a 6-pin and a 8-pin connector.

The 500W power supply requirement is the same one that Gigabyte assigns to the existing R9 285. Let's hope that this is not a straight rebrand - even with 4GB of RAM, that's not going to compete. The fact that the box shown here is for a R9 380 (non-X) seems odd. If someone was going to leak something then why not the 380X?

380 implies Tonga Pro, not XT. A Tonga XT would imply a 384bit interface, meaning 3GB VRAM. And nobody wants to release a 3GB card because devs don't want the VRAM pool being splitted up further. Makes Texture creation with only 2/4GB pools available more straightforward. Hence, there also won't be a GTX 960 Ti as a pendant.

Not this again. There is absolutely no evidence that Tonga has a 384-bit memory interface. Apple gets the best (fully enabled) Tonga chips for the Retina iMac, and they have 4GB of RAM on a 256-bit bus.

And It would be just fine with a 256bit bus, I've never found a benchmark that showed a lick of difference on my 7950 with a 384bit bus and overclocking the Vram which goes well above 1700. A 4gb 256bit card with the texture compression should suffice just fine with a "full" Tonga.

With GTX 960 4GB costing like $250(Germany) this would be an easy duel for AMD to win.

Full Tonga is definitely faster than 960.
4GB 128 bit vs 4GB 256 Bit.
Power Consumption close enough to not make real difference.


The next step would be the 970..which still has bad rep for the Vram..but pricing + Performance is all that matters in this end.
But in the end...at least over here in Germany the 970 is like $350 minimum unless you get super lucky on find a special deal (but then you might end up with a model that has a terribly cooling solution yadda yadda).

So again... at least for us Eurohags there is a big chance that Full Tonga is gonna fit right inbetween 960 and 970...if the pricing is right then this might be their actual money maker for the 300 series.



Long story short...in THEORY that card does not have any real competition right now...which is great.

Full Tonga should've been released like yesteryear...but I guess they had to hold back to not have an entire lineup of rebrands for RX 300.



Edit: I still don't see where a 960 Ti would come in , price wise. Not to mention @ 3Gigs I expect it to have some funky 196 bit interface...but what kind of chips would they be? Wasn't the 960 already a new SKU that is actually the full chip? A further cut down 980?

For my August build I'm not sure whether to get Tonga XT since its a stop gap gen, or break the bank for Fiji. Maybe Grenada / updated Hawaii has all the benefits of Tonga, since that'll get me inbetween performance.

Single 8pin? Are there any other card that use this? If I remember tonga had 2x6pin or 6+8 pin depending on the model

So will this be the card for us mere mortals who want to spend less than $300 on an upgrade? I'm so tired of all the 980ti/Fury noise and Nvidia's 970 4*GB nonsense.
